Another approach could be too simply pass the labelled indices in a dict as a third/fourth positional argument.
Why would we want to even consider a new approach to handling keyword arguments which applies only to three dunder methods, `__getitem__`, `__setitem__` and `__delitem__`, instead of handling keyword arguments in the same way that every other method handles them? That's not a rhetorical question. If there is an advantage to making this a special case, instead of just following the same rules as all other methods, I'm open to hearing why it should be treated as a special case.
So for indexing
b = arr[1, 2, a=3, b=4]
Instead of
__getitem__(self, (1, 2), a=3, b=4)
Just do
__getitem__(self, (1, 2), {'a': 3, 'b': 4})
That would be the effect of defining your method with signature: def __getitem__(self, index, **kwargs) so if you specifically want all your keyword arguments bundled into a dict, you can easily get it. -- Steven
